In the meantime, my router is still as useless as it was 3 days ago. I'm sure I could just go buy another router and it'd work. But after sinking so much time into a project, accepting defeat from Comcast just sucks.

Thanks for taking the time to post this. It sounds like you ended up in exactly the same hole with Comcast's technical support that I ended up in. They simply don't understand that this sort of problem is possible - technically or culturally. Its good to know that I'm not the only one (although on some level I was sure that wasn't the case but I imagine most people don't know enough about their equipment to know that their router isn't broken and that Comcast is wrong.)

Two questions:
1. If you reflash with the linksys firmware can you get a lease?
2. Did you try changing your MAC address? And that didn't work?

I'm assuming the problem that I have is MAC based, as my way of dealing with it is to swap back and forth between two different routers everytime this occurs. Perhaps something more subtle is going on besides a MAC address change when I swap those routers, but without someone on Comcast's side to troubleshoot I'm kind of shooting in the dark.
